The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5 allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a "double fetch" vulnerability. La función saa7164_bus_get en el archivo drivers/media/pci/saa7164/saa7164-bus.c en el kernel de Linux hasta versión 4.11.5, permite a los usuarios locales causar una denegación de servicio (acceso de matriz fuera de límites) o posiblemente tener otro impacto no especificado por el cambio de un valor predeterminado de número de secuencia, también se conoce como una vulnerabilidad de "double fetch". • http://www.securityfocus.com/archive/1/540770/30/0/threaded http://www.securityfocus.com/bid/99619 https://bugzilla.kernel.org/show_bug.cgi?id=195559 https://github.com/stoth68000/media-tree/commit/354dd3924a2e43806774953de536257548b5002c https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://usn.ubuntu.com/3754-1 • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2017-7895
The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c. Las implementaciones de los servidores NFSv2 y NFSv3 en versiones del kernel de Linux 4.10.13 y anteriores, no realizan ciertas comprobaciones de la parte final de un búfer lo que permitiría a atacantes remotos desencadenar errores de aritmética de punteros o provocar otro impacto inespecífico a través de peticiones especialmente diseñadas.

Memory leak in drivers/media/video/videobuf-core.c in the videobuf subsystem in the Linux kernel 2.6.x through 4.x allows local users to cause a denial of service (memory consumption) by leveraging /dev/video access for a series of mmap calls that require new allocations, a different vulnerability than CVE-2007-6761. NOTE: as of 2016-06-18, this affects only 11 drivers that have not been updated to use videobuf2 instead of videobuf. La pérdida de memoria en drivers/media/video/videobuf-core.c en el subsistema videobuf en el kernel de Linux 2.6.x hasta la versión 4.x permite a usuarios locales causar una denegación de servicio (consumo de memoria) aprovechando el acceso /dev/video para una serie de llamadas mmap que requieren nuevas asignaciones, una vulnerabilidad diferente a CVE-2007-6761. NOTA: a partir de 18-06-2016, esto afecta sólo a 11 controladores que no se han actualizado para utilizar videobuf2 en lugar de videobuf. • http://linuxtv.org/irc/v4l/index.php?date=2010-07-29 http://www.openwall.com/lists/oss-security/2015/02/08/4 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=827340 https://bugzilla.kernel.org/show_bug.cgi?id=120571 https://bugzilla.redhat.com/show_bug.cgi?id=620629 • CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.8EPSS: 2%CPEs: 12EXPL: 0CVE-2017-7645 – kernel: nfsd: Incorrect handling of long RPC replies
https://notcve.org/view.php?id=CVE-2017-7645
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. El servidor NFSv2/NFSv3 en el subsistema nfsd en el Kernel de Linux hasta la versión 4.10.11 permite a atacantes remotos provocar una denegación de servicio (caída de sistema) a través de una respuesta RPC larga, relacionada con net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c. The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of-bounds memory access. • http://www.debian.org/security/2017/dsa-3886 http://www.securityfocus.com/bid/97950 https://access.redhat.com/errata/RHSA-2017:1615 https://access.redhat.com/errata/RHSA-2017:1616 https://access.redhat.com/errata/RHSA-2017:1647 https://access.redhat.com/errata/RHSA-2018:1319 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e6838a29ecb484c97e4efef9429643b9851fba6e https://github.com/torvalds/linux/commit/e6838a29ecb484c97e4efef9429643b9851fba6e https://help.ecostruxur • CWE-20: Improper Input Validation CWE-130: Improper Handling of Length Parameter Inconsistency •
